[Freesurfer] recon-all -all error with version 4.5

Dear all, I am encountering a problem with 'recon-all -all' with one subject using freesurfer version 4.5 which I did not encounter when using version 4.4. With the older version, the stream ran without error, whereas the processing produces the following error with version 4.5: ##

Re: [Freesurfer] Best way to convert Philips par/rec to mgz

Dear Julie, The easiest way to preserve your data type would be to ask your Philips representative to switch DICOM export to 16 bit representation of the data. Alternatively, if you have access to an EasyVision console, you could try converting your .PAR/.REC into Analyze files with Philips' own

Hi, I've made an average of my subjects using make_average_volume. I've registered each subject's orig.mgz with native-space diffusion images, and created a label-like binary image (1 for included voxels, 0 for everything else) which is in diffusion-space. I can register this back into the subjec

1. No, if the surface is correct you are fine. 2. Not positive what you mean, but it looks fine to me. 3. The green is usually the "orig" surface, not the ?h.white one. This is also a non-cortical region, so I wouldn't worry about it cheers Bruce On Wed, 18 Nov 2009, Lena Palaniyappan wrote:

I had got the same error output with v4.50 but not v4.01 for one of my subjects. I guessed that something might be wrong with the skull-strip process. So, I ran this step with different wsthresh values (from 20 to 30, increased by 1), and found that the brainmask looked very similar if the wsthresh

Hi Africa, -nonormalization flag skips the step where T1.mgz is generated which is causing the error, as you mentioned. 001.mgz initiates the recon-all, but there are several other steps and files generated in the process. Please refer to this wiki to see which steps and the output at each st

Hi Africa, even if the script completed I doubt that it would generate reasonable results without intensity normalization. You are better off using the expert options to make it a gentler normalization (e.g. running mri_normalize with -b $n -g $g where n < 10 (the default) and g < 1. This wi
